WebNov 21, 2024 · At low speeds, the air flows splits when it meets an object and, providing the object is reasonably aerodynamic, flows right around it, closely following its outline. But the faster the air flow and the less aerodynamic the object, the more the air flow breaks away and becomes turbulent. That's what we mean by form drag.
